Which one of the following 802.11 PHYs is more likely to be used in an industrial deployment but not likely to be used in standard office deployments?
Which one of the following 802.11 PHYs is more likely to be used in an industrial deployment but not likely to be used in standard office deployments?
The 802.11 PHY SIG (S1G) is specifically designed for industrial applications, including automation, IoT, monitoring, and control scenarios. It is not commonly used in standard office deployments, which typically utilize PHYs such as VHT, OFDM, and HT that operate in the 2.4GHz or 5GHz frequency bands.
The option would be S1G, which is oriented for either industrial automation, IoT, monitoring and contol scenarios.
Should be A
SIG isn't a listed PHY modulation and HT/VHT are currently used in office, so this only leaves OFDM
OFDM is not a PHY rate, so the only real correct answer is HT
I think it is D as you would think an industrial area would mean long distances and wireless devices that may not support 802.11ac. Therefore you would 2.4GHz and therefore HT.
Plus you would use VHT (802.11ac) and 5GHz in an office environment.
Answer is A. All other 802.11 PHYs operate in either the 2.4GHz or the 5GHz frequency bands, which are used for office deployments.
